Which is more of a limit of clock speed, signal propagation or transistor switch time? I know heat dissipation is a large factor.

- thechao 4y agoCompactness and timing. I don’t know why picosecond switching is a big deal, here? A 3Ghz part with a transistor depth of 40 would require a top end switching rate of 8 picoseconds — and that’s really going to make PD unhappy, as it’d leave no timing margin. At best, this tech is 2–4x faster than the device in your pocket; it’s probably slower, knowing the timing rates of some of the analog-on-digital parts being shipped, right now.

I haven't read the article yet, but I can imagine a chip with watercooling microfluidic channels, possibly also used to transmit informations (kind of like hormones in the bloodstream). If it is useful as a computing medium why not? Would it make a good waveguide too?
